DNS_Probe_Possible_II

When trying to access the site http://iwrconsultancy.co.uk/ I get a This Site Can’t Be Reached page with this comment:

iwrconsultancy.co.uk ’s DNS address could not be found. Diagnosing the problem.
DNS_PROBE_POSSIBLE

I’ve actually tried to visit the website on other browsers to no success.
Chrome:

DNS_PROBE_FINISHED_NXDOMAIN

Pale Moon:

Server not found

Pale Moon can’t find the server at iwrconsultancy.co.uk.

Check the address for typing errors such as ww.example.com instead of www.example.com
If you are unable to load any pages, check your computer’s network connection.
If your computer or network is protected by a firewall or proxy, make sure that Pale Moon is permitted to access the Web.

Internet Explorer:

Can’t reach this page

The DNS server might be having problems.

Error Code: INET_E_RESOURCE_NOT_FOUND

Are you using a VPN? If so, I recommend that you change servers and try again. That always fixes it for me. If you are participating in Brave Rewards, make SURE you select a VPN server that is in the same region as your physical location, or your Brave Rewards will likely be flagged and suspended.

Which technically correct here. Is the site’s DNS A record not setup?
